The process is detailed. If you don’t adhere to every particular in the process, you may get a rejected application, and you’ll incur added expenses. Most adoptive families do not have money to waste on unnecessary fees. Therefore, you need someone who will get it right the first time. Furthermore, adoption law differs from state-to-state. If you’re adopting in a state outside of your home, the laws could be different from what you expect. It’s better to hire an attorney.
One point that Matt mentioned that I found interesting, and certainly gives the service credibility, is that they have lawyers that use their service as well. The lawyer will sell the service to a client for thousands of dollars and then pay RapidAdoption.com to prepare the paperwork for them. There are some that they work with regularly and have an agreement with and some that just purchase the service from their website and give the paperwork to their clients as if they had done it.
